(erst-207i` This invention relates Ito "a `seed."tharvester ing machine, "andis more especially related to a harvester having means for attaching the `front end thereof to a sickle bar :of a mowing mar Figure 4 is a top pian view ofthe harvester;`

adapted to be attached to la conventional mowr chine, the harvester having wheels` fo1?support t ing the same and for driving the feeding mecha-f` nisrn rfor feeding the cut vegetation. backwardly over a perforated screen.,y The harvesterjis especially adapted for harvesting of seed from lespedeza, clover, and other seed crops. e r .e This 'application t is e an improvement. of `the structure shown inmy patent application, Serial Number 211Q650, filed June 3, 1938, `fm' Seed har-L vesting machine, and allowed on March 28, `1939, L

but which did not mature into a patent' on account of my inadvertently failing to pay the iinal fee.

seed harvester adapted to be secured to )the sickle bar of a mowing machine, and having a the raking members being drivenby the ground wheels of the harvester, and the upper portion of the harvester being quickly tiltable upwardly to expose the seed boxbefore the perforated`A be easily and 'quickf e screen so thatthe seeds can ly removed therefroni;

It is another object of this invention to pro` `vide a seed harvester adapted to `'beattached It is an object of tnieinvention to .provide e" to the sickle bar of a mowing machine, and having ground Wheels for supporting the seed harvester, the harvester having means for propelling the cut vegetation rearwardly over a perforated screen, and` said propelling means being driven by the ground wheel, and the upper part of` the harvester being adapted to be lifted upwardly on a suitable `pivot `disposed at thefront` of `the mar chineito `expose the seed box to View, so that it becomes easily accessible for removingl ,the

harvested seeds from the seed box. l

`Some of theobjectsof the invention having right-hand portion of Figure 5,

@Figure 9 is a `vertical Section-a1 view tnrongn the right-hand ground Wheel taken longitudinalf` 1y or the axle;

`ligure 10 is a sectional View taken along the line" IU-IIJin Figure9. f Referring more specifically to the drawings, the numerals I I'I` and Il indicateground `Wheels which are mounted on an axle I 2 passing through the lowerportion of the machine. The yaxle is mounted in any suitable manner in the sidewall frameworks of the lower portion of the appa` ratus, such as bya split bearing I3 disposed on the longitudinal outside bottom frame pieces I4 of the `seed box of the apparatus. Thelower `portion of themachine or seed box alsohas longitudinal `frame members I 6, I1, and I 8 disposed intermediate the sides ofthe apparatus, and has uprising corner posts 20 and 2l with` uprising `center posts 22,` and it also has `forwardly sloping topframe members 23 `and 24 at the sides thereof anda center longitudinally dismember 25. These' frame members posed frame project downwardly, Iand have "their `front ends resting on the` transverse front frame member" 26. 'A suitable protective bottom such `as `a piece of sheet.metal 21 is secured on thebottom sides of the bottom frame members., Side wall members 28 and 29 and rear wall member 30 complete the' seed box `of the apparatus. A` bottom such, as a piece of sheet metal "3| is` r secured over theframe members I4, I6, I'I, and

been stated; other objects will appear yas the det scription proceeds; when taken in connection with the accompanying drawings, in which- Figure lis alside elevationof the apparatus; r Figure 2 is aftransverse sectional view taken along'the line `2 2 in `Figure 1i and` omitting the raking bars, and `also wheels 0f the harvester;

Figure 3 is aside elevational view similar to Figure 1,*butshowing the top portion ofthe harvester in! raised position, and omitting `the omitting` the ground 5o `face of annular hub member' I8. Both of the wheelsare used for a driving wheel, and thereforemust have a special mounting on `the axle. This mounting is. shown" in FiguresgQand 10` wherein a hub 35 is provided having a-plurality or pivoted dogs 36 which are urged'by a compression spring 31 to engage ratchetnotches 38 disposed on the interior sur- 39 of the wheels I 0 and IIS` axle I2 by meanssuch as a cotter pin 43. The

t 2,366,621@l f `Figure 1, omitting the view taken The hub 35 is xedlysecured on axle I0 by any suitable means such as a set screw-40.` A hub rcap 42 is loosely secured on one `rake bar attached near its front end to y each crank on the crank shaft, means sldably supporting the rear ends of the rake bars at the rear end of the upper iframe, `a sprocket i asickle bar of a mowing machine comprising` a wheeled lower frame having an axle transversely 1 and rotatably supported therein, a pair of ground wheels on the end of the axle for supporting the framework, the frame having its upper surface open and the upper edge of the sidewalls sloping forwardly to substantially merge `with the bottom of the lowerfraine, a plate secured to the lower front portion of the frame, and having means for securing the same to the sickle bar of -a mowing machine, an upper frame pivotally t secured to the lower `forward portion ont the` wheeled `frame,` and having a perforated bottom extending thereacross, the front edge of the-bottom being pivotallysecured to said plate, a crank shaft having a plurality of crank arms thereon. i

and being rotatably mounted inthe upper forward portion of theupper frame, a plurality of rake bars pivotally mounted at their forward ends on the cranks of the crank shaft, means disposed transversely or the upper frame for slidably supporting the rear portion of the rake bars, i

the upper frame being capable of pivotal upward and forward movement to uncover the lower frame, and vesca-pementsbetween the ground wheels and the axlefor driving the axle from the wheels, a driving connection between the axle and the crank shaft for imparting rotation to the crank shaft. y
